They are designed to place on the surface of the cortex. rectangular grids with a number of electrode contact points. The electrodes are made of platinum or stainless steel. Thin sheet of flexible translucent Silastic™ rubber. They consist of a number of disk electrodes mounted on a Subdural electrodes to localize epileptiform activity and to mapĬortical function. Head frame for easy three-dimensional positioning. Wicks that may be held in place swivel joints mount on a bracket of a These electrodes consist of metal balls or saline-soaked They apply directly onto the surface of the exposed cortex.
EEG ELECTRODE PLACEMENT SKIN
There are insert into the capillary bed between the skin and the skull bone.Ĭortical electrodes are uses during neurosurgical procedures such asĮxcision of epileptogenic foci.
